2. Recycle mode doesn’t work, and recording stops.
¾ Exit Main System, and run RepairLog500.exe from the system folder to fix this problem.
¾ Check Properties of the folder used for saving video files. Make sure the Read Only
option is disabled.
3. Passwords are lost. Cannot access my GV-System.
The loss of passwords can be solved in the following two ways:
¾ Retrieving password through e-mails.
¾ Removing password database by using the PassUNINStall.exe utility and rebuilding all
accounts.
However, if both Send Password by Email and Allow Removing Password System
options are not selected in advance, it is required to reinstall Windows operating system
once you loss the passwords. See 1.5 Account and Password.
4. A message “Directdraw overlay fail” appears.
¾ Make sure your VGA card meets the GV-System’s minimum requirement that is NVIDIA
GeForce II MX 32MB.
¾ The driver included in your VGA card package may not be the latest and might not
support Directdraw. Visit related websites and upgrade your VGA driver to the latest
version.

disable DireDraw Overlay, click the Configure button, select General Setting, select
System Configure and disable Enable DirectDraw Overaly.)

¾ Enable De-Interlace Render (Click the Configure button, select General Setting, select
